指逆變器并聯(lián)連接在市電與負(fù)載之間，起后備電源作用，同時(shí)逆變器作為充電器給蓄電池充電。通過逆變器的可逆運(yùn)行方式，與市電相互作用，因此被稱為互動(dòng)式。此種UPS電源，在市電正常時(shí)，負(fù)載由經(jīng)改良后的市電供電，同時(shí)逆變器作為充電器給蓄電池充電，此時(shí)逆變器起AC/DC變換器的作用；而當(dāng)市電故障時(shí)，負(fù)載完全由逆變器供電，此時(shí)，逆變器起DC/AC變換器的作用。 </p> <p> 在線互動(dòng)式UPS具有結(jié)構(gòu)較簡單、實(shí)施方便、且易于并聯(lián)、便于維護(hù)和維修、效率高、運(yùn)行費(fèi)用低、整機(jī)可靠性高等優(yōu)點(diǎn)，性能滿足某些負(fù)載要求，特別適用于網(wǎng)絡(luò)中某些計(jì)算機(jī)設(shè)備采用分布式供電的系統(tǒng)。此種電源缺點(diǎn)是穩(wěn)壓性能不高，尤其動(dòng)態(tài)響應(yīng)速度低，其次抗干擾能力不強(qiáng)，電路會(huì)產(chǎn)生諧波干擾和調(diào)制干擾。
